When he woke up, he found himself naked in an ancient royal bathhouse! A group of palace maids and eunuchs were stunned, while the young emperor was even more frightened and trembling. Gu An's "otherworldly" modern bathing habits and "unheard of" physics knowledge were mistaken for the coming of an immortal. In the crisis-ridden palace, he was semi-forced to be canonized as the "Immortal Protector of the Country" and shouldered the heavy responsibility of saving the crumbling dynasty.
[All Things Analysis System] was accidentally bound, and Gu An's modern wisdom was infinitely amplified. From "soap purification" to "glass mirror", from "steam engine" to "gunpowder innovation", he is no longer a mortal fighting alone, but a true god with technological plug-ins! Faced with the conspiracies of powerful ministers, barbarian invasions, and raging natural and man-made disasters, Gu An had no choice but to act as a "scientist" in the name of "immortal master". He will set off an unprecedented technological revolution, ignite the ignorant old world with the spark of modern civilization, and transform this backward dynasty into a new empire like a giant steel ship! However, as he uncovered the truth behind the time travel step by step, he discovered that there was far more hidden in the depths of history than a simple dynasty change...
